Does Keto Raise Cholesterol?

October 14, 2019 0 By William Morgan

– You might be concerned that when you go
on a low-carb/high-fat ketogenic diet
that your cholesterol is going to go up.
And if you look at conventional medicine
and conventional research,
that’s going to have you alarmed.
Well here’s the thing.
Cholesterol is not a bad thing
and there’s a very good chance
that when you first
start a ketogenic diet,
you will see an increase
in your cholesterol levels,
both good and bad.
But when you stick with me
through the end of this video,
you’re going to realize
that that’s not a bad thing
and that actually means you
could be burning more fat.
Hey, I’m Thomas DeLauer with Keto-Mojo
and today we’re going to be breaking down
the science of cholesterol
and its relationship with
keto and inflammation.
You see, let’s go ahead and
start off with one study though,
it was published
in The American Journal
of Clinical Nutrition,
took a look at 118 participants.
Now with these 118 participants,
they divided them into two groups,
a low-carb group that was also
high fat and a low-fat group.
They wanted to see who
would lose more weight
but they also wanted to look
at typical blood markers.
They found that the low-carb group
at the end of the study ended
up losing over 32 pounds
whereas the low-fat group still
lost a good amount of weight
but they only lost 25 pounds,
so not as much as the
low-carb/high-fat group.
Okay, that’s great,
but what does this have
to do with cholesterol?
Well they found that the low-carb group
had a decrease in triglycerides,
now triglycerides are
the storage form of fat,
we want that number to go down,
that means we’re good, healthy people.
But they did see an increase in HDL
which is the good cholesterol,
and a small increase in LDL
which is technically the bad.
So they had an increase
in both good and bad,
now if you understand cholesterol,
you know that the HDL
is the good cholesterol
that removes the
cholesterol from the blood,
and the LDL delivers it.
So if we have an increase in HDL
but we also have an increase in LDL,
it really is no real difference, right?
So here’s what’s interesting though.
We have to understand what
happens with the ketogenic diet.
When our body is mobilizing fats,
what’s happening is a lot of these cells
are expressing more cholesterol,
so as we are getting fat adapted
and as we are getting a bit more
in the way of free fatty acids
and triglycerides are getting mobilized,
we will see a subsequent
increase in cholesterol.
However, it’s associated
directly with fat burning, okay?
Now whether you’re doing keto for fat loss
or just for cognitive,
or just for long-term lifestyle changes,
you’re going to see a little
increase in cholesterol
and then it will balance back out.
Once your body becomes fat adapted,
there’s no need for the
cholesterol to be elevated,
so you see with a lot of
people that start keto,
they get a quick bump in cholesterol,
they get a little bit concerned,
and then if they stick with
the keto diet for a few weeks,
that comes right back down to baseline.
The important thing is
that our triglycerides
are going down,
that is the one that
could be dangerous for us.
Now let’s take a look at how cholesterol
is actually absorbed because
this is where it gets wild.
Our dietary cholesterol,
cholesterol that we get from eggs,
from bacon, from some
of these saturated fats
and even different plant cholesterols,
really don’t end up having an
effect on our blood levels,
you see, it’s way too hard to absorb them,
but even more importantly,
we have to understand that our bodies
have a natural set point,
a natural homeostasis of
cholesterol, if you will.
So what that means is 75% of
the cholesterol in your body
is made by your body,
only 25% of the total
cholesterol in your body
is derived from the food you eat.
Every single cell in your
body creates cholesterol,
it’s that important.
And of all the cells in your body,
only 20% of the cholesterol
is actually made in the liver,
80% of it is made throughout
the rest of the body
because it’s that vital.
So what happens is when
we consume cholesterol,
it has to be in what’s
called an unesterized form
to even be absorbed.
Now most of the cholesterol
that we end up having
in our digestive track ends up
being what is called esterized,
all that means is is put
into blocky molecules
that are too big to fit
through the enterocytes,
too big to fit through
our intestinal cells.
So they end up going
through the digestive system
and then getting recirculated
into the way of bile,
the liver and then
ultimately the gallbladder.
So really, they’re just
there for digestion purposes.
So only a small amount
actually gets absorbed,
so the whole idea of
consuming dietary cholesterol
and raising your blood
levels of cholesterol
is completely wrong, okay.
We have genetic predispositions
to our levels of cholesterol
and it doesn’t necessarily
mean anything good or bad,
so here’s what we have to
understand: oxidized LDL, okay.
Bad cholesterol is not really that bad,
in fact we found that LDL
is actually quite good,
it delivers cholesterol to what’s needed,
steroid hormones to actually
create important things,
pregnenolone, testosterone,
all these things that are
vital for our survival.
What ends up happening is
when LDL becomes oxidized
from things like sugar
or things like stress,
the LDL that is oxidized
becomes the problem.
Oxidized LDL can bury itself
inside an artery ultimately
and what ends up happening
is when it’s oxidized,
it triggers a lot of white blood cells
to come to it and flock
to it and swell it up.
And the when it swells it up,
it can calcify and have a whole reaction
of white blood cells that
triggers a clot to form.
It’s not LDL specifically,
it’s specific forms of LDL
that have already been oxidized by stress,
by sugar and by other free radicals.
So typically, with the ketogenic diet,
when you’re reducing the
reactive oxygen species
and reducing the overall
stress in the body
and reducing inflammation,
the LDL that is elevated
isn’t as potentially bad,
so you’re in a great position.
Now the ketogenic diet as
a whole produces ketones
and ketones are anti-inflammatory,
which makes so that the LDL
does not become oxidized
because it’s able to fight
off the inflammation.
So how do you know if you’re in keto?
Well, of course that’s where
the Keto-Mojo meter comes in.
You want to be able to
test your blood ketones
and you want to be able
to know where you’re at
and make sure that you’re producing
enough of these oxidizing buffers
that are going to prevent LDL
from becoming oxidized
and becoming a problem.
So it’s not about your
cholesterol being high,
it’s about your
cholesterol being mobilized
and it’s about getting your
body in the right state
to fight inflammation.
And with that, you need ketones.
So make sure you leave
the measuring to the meter
so you always know where you stand
to make sure you’re getting the
most of your ketogenic diet.
